IMPROVEMENT IN SASH-HOLDERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.- l

Be it known that we, WILLIAM G. JONES and SAMUEL M. RANKIN, of Long Green, in the county of Baltimore and State of Maryland, have invented a certai-nnew and useful Improvement in a Window- Sash` Holder and Lock; and the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing making a part of this specification, in which- Figure 1 represents the inside view of a windowframe and sliding sash with a portion of the casings broken out, showing the mode of inserting the friction sash-holders in` the window-frame.

I `igure2 shows a vertical edge view of the two sashes and window-frame, with a`stop and lock-catch in position.

Figure 3is an enlarged broken-ofi' section of one side of a window-frame, showing the lock catch-pin, to fasten the, upper sash, closed.

Figure 4 shows a perspective view of the lock-catch combined with a friction sash-holder detached.

Figure 5 shows a perspective view of' one of the combined metallic and velastic-block friction sashnp or down, and will hold either upper or lower sash in any desired position, and lock them both firmly when closed, so that they cannot be unlocked or opened from the outside.

To enable others' to make and use our invention, we will describe it more in detail, referring to the drawing and to the letters of reference marked there- The elastic or yielding block A is best of vulcanized India` rubber, wrought or cut into any form suit-v ableJ and of suchY dimensions as necessary to effect the purpose.

The diction-plate B may be made of anykind of sheet metal, out in strips of suitable width to cover the outer surface ofthe yieldingr block A, the ends b b being bent over at right angles to clasp onto the ends of the block A, secure `it. sufficiently thereto, so that no other fastening is required.

The metal plate G, that forms the lock to hold the sash from being moved, is secured to the. yieldingblock A by a single rivet, a, the lower end, b', being bent at a right angle; the upper end extending up in a plane, making the plate C twice the length of the other plates B, the top end being bent over outward, forming a catch or hook, D, and a thimble in which to secure a pin, d, which extends back into a small notch, e, made in the front-edge corner of one side of thenpper sash E,'aud locks it rmly closed; while at the same time the catch D hooks' over on the upper corner of the lower sash F and locks 'it closed in the samemannelyso that neither sash can be opened frein the outside of the window, or moved until the catch D and pin d are forced back into the recess made in the window-trarne G, when both of the sash are unlocked, and eitherone may be moved at pleasure, the friction-plates B bearing suiiiciently against the edges of the' sash to hold it in any desired position it may be placed and'r left, the size of the stops, and the power of tl'ieiiyinessure being adjustable to compensate the weight of the sash.

It' desirable, for the convenience of unlocking, the pin d may extend out in front by the inside casing a sutlcieut distance to i'orin a knob.

The advantages of our combined metallic and elastic window-stop and lock are, that they are more simple in their construction, and are more easily applied and fitted to windows, requiring no fastening in the recesses ofthe plane; the pressure is'nnore easily ad justed and uniform upon the sash; they keep the windows still, from making any noise when being opened, or rattling when closed; they are as cheap, or cheaper, than any other; and will be as durable as anything for-the purpose that has yet come to our knowledge.

` We are aware that vulcanized rubber has been applied as rollers, and in various forms, and also metal springs, of almost all conceivable forms, which we do not claim broadly, separately, or combined; but

What we do claim is- The combination of thev metallic friction-surface plate and elastic block with the catch D and pin d, when these latter are attached to the plate and block, for locking both the upper and lower sash, substantially in the manner shown and described, for the purpose set forth.

In testiinony whereof wejointly subscribe our names in the presence of- WVM. G. JONES. Witnesses: SAMUEL M. RANKIN.
